If what you are doing is improving your tank condition stay the course but at some point you need to stop the chemical band aids and focus on water stability with appropriate parameters. None of these things happen overnight. It may take months for you to find the right combination to balance your system. It is common for 0 nitrates to cause tank problems and negative coral health so at some point you need to address that or problems will arise.Brs site says for use with mb7. So your saying I could stop using the mb7 see if nitrates rise and if not add then add Neonitro?
